如何在php中实现请求和响应

I have URL like this, how we recive the value like "abc.org/result.php?rq=[1,2,3,4]&rq1=[5]" etc

Can any one help me to convert rq into array when recive the value in result.php

You can try using explode() & array_map()

$rq = $_GET['rq'];

$arr = array_map(function($v){ return trim($v, ' []');}, explode(',', $rq));

print '<pre>';
print_r($arr);
print '</pre>';

You can use json_decode to convert into array

$a = json_decode($_GET['rq']);
print_r($a);//Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 )

You can use get request also:

Abc.com?req[]=1&req[]=2

$_GET['req']
Return 
(1,2)
